Replaced the 219A in my D25A with an XPL HI V2 5B4 and added a bit of solder to the positive contact so I could use a flat top Efest 14500. Warmer tint, higher output, runs cooler.
Also put the same LED in my Kronos X6 and bypassed the springs.
Unfortunately I only have one left and it doesnāt look like Iāll be able to get anymore.
I put a fet+1 in a XinTD C8 7135 that has a XM-L U3 1A led in it. Itās a little brighter.
I received an xtar charger that failed when the AC adapter was plugged in. Xtar warrantied charger and I told them Iād destroy the first since I couldnāt send it back as they requested. The shell, messed up circuit board and sliding contacts remained, so, I built a charger/light combo using a 4056 charger and half (4.2V) of a messed up MTG2 LED. 
The left ābayā is the charger and the right bay has a 3x 7135 driver powering the LED. The ādiffuserā is piece of a toothbrush case stuck down with double sided tape.
thatās one of the weirdest things Iāve seen someone make on BLF 
In charger lighting!
:dance:
Part of the reason was that I didnāt have a single 26650 light so instead of spending moneyā¦
Stacked some chips on a stock Convoy C8 driver.
I installed an A6 driver in a Nitefighter 502B. Driver ring was jammed so I drilled the driver and left it in place. Filled the gap with wire and soldered. The spring actually needs to be clipped but I chose to put a thicker Oring and all is well. I really do like the A6 driver. Wish the Bistro was available. Nice light now!!
Built a Trustfire Mini 01 triple today with some spare parts i had.
Copper & QTC pill in the tail for variable output, Also made a copper head spacer.
I didnāt realise the 3 XP-G2 were different tints until i had it put together, doh - i think thereās maybe a 2B, 2C and 1A in there, not entirely sure. :-/
This bothers my CDO so i will call it an intended tint balancing feature 
Also ground off the keychain attachment and installed a magnet in the tail and some heatshrink around the body.
Nice mod CRX! I have some QTC pads waiting for a mod still.
Thanks djozz, yeah the QTC pills come in handy for when you accidentally break drivers.
Is the whole light copper or is that just the lighting?
Just my terrible photography mate.
TBF tint balancing feature. I like it. Maybe make a bezel cover with single hole so you could rotate it to select you desired tint 
Pure genius
I made a butter knife into a steak knife in four minutes to demonstrate the effectiveness of my Ken Onion Worksharp .
Have I mentioned how much I like this tool ?
:face_with_monocle: 
Kinda forlorn here since I donāt have the time to do any modding, as we are moving to a new home, and all my parts and tools are put away.
I just replaced the reflector on my original first-ever high-power LED flashlight purchased, an original UltraFire 501b, with an EZ-900 XR-E R2 emitter. I swapped the P60 OP reflector with a spare SMO I had handy. I had forgotten what kind of beam this light would make in this configuration. It was slightly ringy, but not as bad as I had expected. Now, it has a very intense and rather well-defined hotspot, making it a surprisingly good thrower. I may eventually add a fourth 7135 to the driver, pushing it just a little bit harderā¦ 
I put an xpg2 into a DST with a 2S, 5A buck driver, finally. Just need to bypass the tail spring to wrap it up. Also prepped a Jacob A60 to receive a dedomed xpg2 because I may have fried the previous oneā¦ whoops. 
I wish people would quit bringing up DSTās. 
Unless they have one to sell , lol
How much cash do you have? :face_with_monocle:
I have one that I offered to sell a while ago, and still might sell. The biggest issue is the shipping will add $10-15 probably. (and I did a few āmodsā to it and made it a little ugly :SICK: ) lol
